Class SecondaryMacroBlock

java.lang.Object

solvers.linearSystem.btf.ComponentBlock

solvers.linearSystem.btf.macroBlocks.SecondaryMacroBlock

Direct Known Subclasses:

XSecondaryMacroBlock, YSecondaryMacroBlock

public abstract class SecondaryMacroBlock
extends ComponentBlock

This class is an abstract super class the implements the common featrues of the SecondaryMacroBlocks that are found in the X and Y blocks of the A matrix. methods for their initialisation and sub copying are implemented. The matrix is represented by a SparseBlockMatrix.
